Corrugated steel pipes (CSP) are a highly versatile and durable solution for a wide range of applications, particularly in drainage and stormwater management. These pipes are known for their strength, longevity, and ability to withstand various environmental conditions. CSPs are available in multiple coatings and configurations to suit specific project needs.
After at home and abroad investigation and collection in recent years , corrugated pipe due to various problems which results in the pipe body damage, severe deformation occur occasionally, in order to prevent such incidents happening again, enumerate five kinds of situations as flowing, hope to strengthen the management of the construction process in the future,
Wedge part with uncompacted backfill, which results in the pipe body bottom flattens.
The pipe body wedge part on both sides and the local part have big stones, leading to local pipe hard cuts or bulge.
Asymmetry of backfill lead duck's egg circle, leading to serious collapsing.
Both sides filling not dense, leading to excessive deformation.
inside of 50cm on both sides of pipe, the backfill material is not up to the requirements, it should fill sand material, but adopt expasive soil or other material, it become soft when it encounter water, then no load capacity, results the pipe body big lateral deformation.
| Corrugation | 68×13mm,100×20mm,125×25mm,150×50mm,200×55mm,230×64mm,300×110mm,380×140mm,400×150mm |
| Diameter or span | 0.4m-24m |
| Thickness | 1.6mm-12mm |
| Zinc coating | 84μm each side |
| Steel standards: | ASTM A36,EN 10111,ISO 5951 |
| Application | .Multiplate structures pipe can be used as: - culverts - bridges - tunnels - under passed - ecological crossing - pedestrian tunnel - hangers - shelter - warehouse - stores for ammunition - belt conveyor protection - ventilating duct - and for reinforcement and reconstruction of existing structures as well. Metal corrugated pipe can be used for every class of service load provided that appropriate back filling is performed |
